Dams Through eight lessons, students are introduced to many facets of dams, including their basic components, the common types (all designed to resist strong forces), their primary benefits (electricity generation, water supply, flood control, irrigation, recreation), and their importance (historically, currently and globally). Through an introduction to kinetic and potential energy, students come to understand how dams generate electricity. They learn about the structure, function and purpose of locAuthor(s): Integrated Teaching and Learning Program,

Just Plane Simple This lesson introduces students to three of the six simple machines used by many engineers. These machines include the inclined plane, the wedge and the screw. In general, engineers use the inclined plane to lift heavy loads, the wedge to cut materials apart, and the screw to convert rotational motion into linear movement. Furthermore, the mechanical advantage describes how easily each machine can do work and is determined by its physical dimensions.Author(s): Integrated Teaching and Learning Program,

Egg Drop A process for technical problem solving is introduced and applied to a fun demonstration. Given the success with the demo, the iterative nature of the process can be illustrated.Author(s): Office of Educational Partnerships,

Copycat Engineers This lesson introduces students to the idea of biomimicry — or looking to nature for engineering ideas. Biomimicry involves solving human problems by mimicking natural solutions, and it works well because the solutions exist naturally. There are numerous examples of useful applications of biomimicry, and in this lesson we look at a few fun examples.Author(s): Integrated Teaching and Learning Program,

Light vs. Heat Bulbs Students measure the light output and temperature (as a measure of heat output) for three types of light bulbs to identify why some light bulbs are more efficient (more light with less energy) than others.Author(s): Office of Educational Partnerships,

We’ve Come a Long Way, Baby! Students discuss several human reproductive technologies available today — pregnancy ultrasound, amniocentesis, in-vitro fertilization and labor anesthetics. They learn how each technology works, and that these are ways engineers have worked to improve the health of expecting mothers and babies.Author(s): Integrated Teaching and Learning Program,

Spacecraft Design: Beat the Heat To understand the challenges of satellite construction, student teams design and create model spacecraft to protect vital components from the harsh conditions found on Mercury and Venus. They use slices of butter in plastic eggs to represent the internal data collection components of the spacecraft. To discover the strengths and weaknesses of their designs, they test their unique thermal protection systems in a planet simulation test box that provides higher temperature and pressure conditions.Author(s): Integrated Teaching and Learning Program,

Riding the Radio Waves Through this lesson students learn how AM radios work through basic concepts about waves and magnetic fields. Waves are first introduced by establishing the difference between transverse and longitudinal waves, as well as identifying the amplitude and frequency of a given waveform. Students then learn general concepts about magnetic fields, leading into how radio waves are created and transmitted. Several demonstrations can be performed in order to help students better understand these concepts.Author(s): Techtronics Program,

Drifting Continents This activity is a teacher-led demonstration of continental drift and includes a math worksheet for students involving the calculation of continental drift over time. Students will understand what continental drift is, why it occurs, and how earthquakes occur because of it.Author(s): Integrated Teaching and Learning Program,

Bombs Away! Students will design and build a device to protect and accurately deliver a dropped egg. The device and its contents represent a care package that must be safely delivered to people in a disaster area with no road access. In a similar fashion to a team of design engineers, students will design their devices using a number of design constraints including limited supplies. The activity emphasizes the change from potential energy to kinetic energy of the device and its contents and the energy transAuthor(s): University, Pratt School of Engineering K-PhD Prog

Water, Water Everywhere Students learn about floods, discovering that different types of floods occur from different water sources, but primarily from heavy rainfall. While floods occur naturally and have benefits such as creating fertile farmland, students learn that with the increase in human population in flood-prone areas, floods are become increasingly problematic. Both natural and manmade factors contribute to floods. Students learn what makes floods dangerous and what engineers design to predict, control and surAuthor(s): Integrated Teaching and Learning Program,
